Sakana Dream Co., Ltd., based in Tateyama City, Chiba Prefecture, will host a tasting comparison event for its "Yume-Aji" farmed fish and "Seki-Aji" natural horse mackerel on April 18 (Saturday) and 19 (Sunday), 2026. The event will take place at select Nakajima Suisan fresh fish specialty stores in the Kanto and Kansai regions, offering a special sushi set. "Yume-Aji" will also be sold individually at all Nakajima Suisan stores during the same period.
"Yume-Aji," which commenced full-scale sales in March 2026, is a novel farmed fish developed from the rare Carangoides equula (Kaiwari) and the high-quality Trachurus japonicus (Kin-Aji) from Minamiboso. It is characterized by its rich umami and superior fat content, often described as "toro of white fish." The farming process uses premium bluefin tuna feed and includes thorough blood-draining before shipment. It is cultivated in Tomuura Bay, Chiba Prefecture, known for strong currents, and Uchiura Bay, Shizuoka Prefecture, rich in nutrients from Suruga Bay's deep waters. A key feature of "Yume-Aji" is its "one-generation" nature, meaning it is infertile and cannot reproduce, thus preventing adverse ecological effects if it escapes into the wild.
"Seki-Aji" is a premium brand of horse mackerel caught by skilled fishermen using single-line fishing in the Hayasui no Seto off Saganoseki, Oita Prefecture. Its quality is maintained through rigorous handling, including "Men-gai" (visual size assessment) and individual live-bleeding, resulting in firm flesh with balanced fat and exceptional freshness.
Sakana Dream Co., Ltd. was established on July 3, 2023, with Shunichiro Hosoya as CEO. It is a fisheries startup originating from Tokyo University of Marine Science and Technology, focusing on the development, production, and sales of new farmed fish.
